I've searched and found people asking this question (like here), but with no results. I see the 4 jack pads on the car, but my question is, where do I put my floor jack in order to put a jackstand at these 4 jack pads?

No, that's not what I'm looking for. My point is, if I put my floor jack at the passenger front jack pad to raise the car, once the car is in the air, how do I get the jackstand in the pad if the floorjack is in the way? I'm not fast enough to pull some kind of sheet trick with the jack and stand; LOL. There has to be another place to put a floorjack, but I don't want to risk breaking or bending anything underneath the car.

I just did this to change out to my winter tires. I placed the jack stands under what I would term the lower A arm that connects from the lower frame to the bottom of the end of the axle. Yeah, not very descriptive, but my point is I was looking for a solid metal piece that could support the weight, so something that didn't move.

The front subframe has a plastic jack pad. It's visible with the plastic splash panels in place, just get under there and look for it, dead center of the car, about equal with the back end of the front tires. You use this to raise the front of the car.

In the back...I'm not sure. Probably the differential. Though I've never been able to convince myself to jack up the car using part of the drivetrain!

Is the 211 supposed to have plastic jack pads mounted on the body? I've not spent much time underneath mine lookiing. The previous half dozen or so MBs I've owned all used the old style Bosch jack with the jackpoint in the rocker panel and a seperate pad underneath the car.

NO, absolutely not!!! It is aluminum, and will break off under the weight of the car. If you have to lift the car by the rear diff, then place a 2x4 under the differential, but not under the cooling fins. I'm glad that, I seen this thread before you made a mistake. The cooling fins can't handle the weight of the car, and the bolts that hold it in place might shear off, ruining your day. The fins might look like a stout piece but trust me, it will break off.

Help at all???

I second this, plus what YUILLE36 said about at least using a 2x4 when raising on Rear Diff....
